Definitions

  • the present invention concerns a method for reduction of nitrogen oxides and sulphur oxides being present in exhaust gas from internal combustion engines by means of a reducing agent such as ammonia and urea.
  • a reducing agent such as ammonia and urea.
  • the invention focuses on the removal of such compounds from exhaust of engines being operated with fuel having high sulphur content .
  • the reduction of NOx to nitrogen (N 2 ) is usually conducted by using ammonia or urea as reducing agents over a suitable catalyst in the so-called selective catalytic reduction (SCR) .
  • SCR selective catalytic reduction
  • Exhaust gas cleaning from turbocharged combustion engines is problematic by the following reasons.
  • Ammonia being the usual reduction agent employed in the SCR of NOx reacts with sulphur oxide also present in the exhaust gas, especially in the exhaust from HFO fuelled engines .
  • the reaction products are ammonium sulphate or ammonium bisulphate, which condense on the SCR catalyst and in- hibit the catalyst upon contact with ammonia, if the exhaust gas temperature is under a certain limit.
  • the temperature of the exhaust gas is typically between 330 and 500°C immediately after ejection from the engine. This temperature is well above the condensation temperature of the sulphates .
  • the relatively high temperature means that some of the S0 2 in the exhaust gas is oxidized to SO 3 across the SCR catalyst.
  • the formed S0 3 together with S0 3 already being present in the outlet exhaust from the engine leads to formation of an acid plume if not captured in the exhaust treatment equipment train.
  • the general object of this invention is to provide a method for the combined reduction of NOx and SOx from tur- bocharged internal combustion engines, without the above discussed problems.
  • the essential feature to the invention is to overdose the amount ammonia in the exhaust gas relative to the amount consumed in the SCR in order to capture SO 3 as ammonium sulphate or ammonium bisulphate in the downstream equipment train or to dose ammonia to create a low slip from the SCR so that S0 3 can be captured as H 2 SO 4 in a wet scrubber .
  • this invention is a method for reducing amounts of oxides of nitrogen and sulphur in exhaust gas from a lean burn internal combustion engine, comprising passing the exhaust gas together with an adjusted amount of ammonia through a catalyst system comprising one or more catalysts being active in the reaction of nitrogen oxides to nitrogen, the ammonia is introduced into the exhaust as such or is formed after introduction into the exhaust gas prior to passage of the exhaust gas through the catalyst system;
  • the exhaust gas is passed through the catalyst system at a temperature above condensation temperature of ammonium sul- phur compounds formed by reaction with ammonia in the exhaust gas and wherein the amount of ammonia in the exhaust gas is adjusted to result in an amount of less than 2 ppm by volume or more than 10 ppm by volume after passage through the catalyst system.
  • the amount of ammonia may be kept less than 0.5 ppm by volume after passage through the catalyst system.
  • the formed S0 3 can be captured as ammonium bisulphate (ABS) or ammonium sulphate (AS) .
  • ABS and AS are water soluble compounds and can easily be removed by scrubbing with water in a scrubber. ABS and AS may also be removed by the use of soot blowing equipment .
  • the scrubber is optimized for SO 3 capture.
  • the ammonia slip is kept at a mini- mum in order to minimize fouling in downstream equipment.
  • ammonia slip from the SCR is kept above 10 ppm by- volume, ammonium bisulphate and ammonium sulphate condensate in a waste heat boiler, either at the heat transfer surfaces or as solid particles in the gas phase.
  • the depos- its formed on surfaces in downstream equipment can be removed by cleaning with water and/or during soot blowing, whereas the particles are removed in a downstream SOx scrubber .
  • the ammonia slip is kept low ( ⁇ 2 ppm) , which means that fouling of the downstream equipment by ABS and AS is minimized.
  • the S0 3 may then be removed in a SOx scrubber that is optimized for S0 3 removal.
  • Ammonia for use in the inventive method can be supplied in the form of gaseous ammonia or by means of a urea solution, which decomposes to ammonia after injection into the exhaust gas.
  • the method according to the invention is in particular relevant in connection with two-stroke engines. Those engines are commonly used on board of marine vessels and fuelled with sulphur containing heavy fuel oil. Example
  • a 2-stroke engine on a marine vessel emits 1500 ppm (volume) NOx, 750 ppm (volume) S0 2 and 15 ppm (volume) S0 3 engine outlet.
  • the engine exhaust gas temperature at inlet to an SCR unit is between 330 and 500°C at a pressure of between 2 and 4 bar gauge.
  • a turbo charger Across the pressurized SCR upstream a turbo charger the NOx level is reduced to below 300 ppm, whereas additional 30 ppm S0 3 is formed.
  • the ammonia slip after the SC unit is adjusted above 20 ppm, which results in ammonium bisulphate and ammonium sulphate formation and condensation in a waste heat boiler downstream the turbocharger, either at heat transfer surfaces or as solid particles in the gas phase.
  • the deposits formed on the surfaces can be removed by cleaning the boiler periodically with water, whereas the particles are removed in a downstream SOx scrubber.
  • the ammonia slip is kept very low ( ⁇ 2 ppm) , which means that the waste heat boiler fouling by ABS and AS is minimized.
  • the SO 3 is then removed in the SOx scrubber that is optimized for SO3 removal.
